GEORGE HENRY DOWNS, OF NORTH POWDER, OREGON, ASSIGNOR OF ONE-HALF TOWILLIAM E. GRACE, OF BAKER CITY, OREGON.

OVERHEAD TRAVELING CARRIER.

To all whom it may concern:

Be it known that I, GEORGE HENRY DOWNS, a citizen of the United States,and a resident of North Powder, Union county, State of Oregon, haveinvented a new and useful Improvement in Overhead Traveling Carriers, ofwhich the following is a specification, reference being had to theaccompanying drawings as constituting a part thereof.

This invention relates to traveling carrier systems comprising anelevated cable or rail, a ycarrier traveling thereon, and a weightsuspended from the carrier.

Tocomprehend the purpose of my invention, I will briefly describe theutility of the same, with respect to an overhead cable, from whichdescription its utility for other purposes, as for example, an elevatedrail, will be self evident.

In the case of an overhead cable, it is desirable to use lateral ropesor stays, at intervals along the course of the cable, to prevent thelateral swinging of the latter; but such arrangement would necessitatethe lifting of the carrier across said lateral stays, unless the carrierwas specially constructed, as in my invention; furthermore, it isdesirable that the carrier be so arranged as to prevent it getting oil'and becoming displaced on the cable While traveling along the same,which occurrence is a most annoying accident.

My invention, therefore, has for its primary object to obtain a carrierwhich is so constructed as to be able to pass over crossing`stay-cables, and is furthermore so constructed that the same cannotbecome displaced on the cable or other track over which it is traveling.

To this end my invention comprises the arrangement and combination ofparts illustrated inthe drawings and hereinafter fully described andclaimed.

In said drawings, Figure 1 is a perspective side elevation of myimproved carrier, representing the same as running on a carriercablehaving lateral stays, and my carrier being seen in the act of crossingone of such lateral stays; Fig. 2 is a side elevation of my carrier withits near side-portion removed, and representing my carrier as trav elingon a carrier-cable and in the act of crossingone of its lateral stays;Fig. 3 is a central cross-section of my carrier, representing the samein a similar situation as shown in the preceding ligure; and Fig. 4

is a sectional detail on a larger scale, showing a modiiied constructionof my carrier, more fully explained in the body of the speciication.

Referring now to the letters as designating the parts described: Mycarrier comprises two sides pieces a, b, by which the load is supported,said sides being starshaped when looked at in side elevation, that is tosay, each has a rim portion assembling radially projecting spokes c. Theinterior opposite faces of the spokes c are respectively made withrecesses (Z,constituting a sort of annular run-way, concentric with theaxis of the carrier.

The central portions of the sides a, b are made with registeringapertures through which to insert an axle-bolt c, secured in place bynuts f, fastened on its projecting ends and made with a centralboss-portion g, on which is journaled a grooved-rim wheel L, the latter'being arranged intermediate of the sides, as shown in the cross sectionFig. 3. Supplementary nuts f are also secured on the extremities of theaxle-bolt e, and between the nuts f, f are secured the members of a yoket, as shown in dotted outline in Fig. l, to which to fasten the cable(not shown). The boss is so arranged that the sides a, b may be jammedagainst the same by the nuts f without binding the wheel it; Suspendedin the annular run-way o1' recesses d, of the sides a, I), is a hangeri, made with lateral shoulders j, convexed on their under surface, asmore clearly seen in Fig. 2, so as to ride on correspondingshouldenportions c, being wall portions of said recesses (l of thespoke-like rims c. In order to reduce the friction imposed by theshoulders y' of the hanger c', upon the shoulders 71,- of

Vsaid spoke-like rims c, it is practical to provide one of the bearingsurfaces with ballbearings.

In the construction illustrated by Fig. 3, the ball-bearings Z, Z areseated in the bearing faces of the hanger z'. Supposing now that mrepresents a length of the carriercable, and n one of the transverse orlateral stay-ropes, and supposing further that my traveling carrier isin the act of crossing 105 011e of such lateral stays, as shown in thedrawings, it will be noted that the spokelike rims c of the sides a., bhave straddled the stay-ropes a, and therefore, as the carrier continuesto move along the cable m,

llO

the sides a, b will be rotated by reason of the contact oftheiriinportionv c with the stay-rope, thus causing the hanger z' topass from one series of recesses el in the sides to contiguous recessesthereof, withpthe result that the hanger will maintain its pendentposition. In otherjvords, the hangerl merely slides from one series ofspoke-likerim portions of the sides to anotherwhile passingjournal-pm, awheel mounted centrally thereon, sldes mounted on said Journal-pmlateral stays.

In the modified construction shown in.

4, the spokes c2 of thev sides a, ZX are made .with-run-Waysor recesseso, arrangedv similar to the recesses cl of the previous ex.-A

, ample, butprovided with flangesv p, andthe hanger q is madefwithcorresponding recesses r, r, so as to be adapted toridein saidrecesses0, on said fianges 21,' and the ball-bearings Vs, s are provided .in`the bear,- ing faces of the spoke-like rim portionsrcg, instead of inthe ,bearing I.faces ofthe hanger g, as in the previous example. Theobject of theilanges p and the correSPQILding-recesses r, rf is toobtainan interlocking,con-v tact between the parts, holding the sameagainst separation by reason o f any lateral wrenching strain.Obviously, either of the constructions described prevents thezwheel tfromleaving the lcarriercable by reason of any accident The load issuspended vfrom the hook u Vof the hangerc'.

I Claim:

l. An overhead carrier consisting of1 a j ournal-lpin, a wheel mountedcentrally thereon, sidesH mounted if on said j ournal-pin exteriorofthewheel, the rims of said sides extending beyond the peripheryof thewheel and constituting rims` therefor, and ,being divided intoaplurality ofspoke-lile rim-y` projections,lspaced apart, so as to beadapt ed to straddle a cross wire, said spoke-like rim-projections beingprovided on opposed faces with a run-way, anda hangeradapted` toAslidein said run-way of the sides.

2. Anv overhead carrier consisting of` a journal-pin, a wheel mounted`centrally thereon, sideslmountedy onsaid journal-pin exterior .of thewheel, the rims ofsaid sides extending beyond the periphery of the*wheel and Iconstituting, rims therefor, and being divided into lapluralityv ofspolelike rimprojections, spaced apart, so as to be adaptedto straddle a cross wire, said spoke-like terior opposed faceswithrecesses constitut-- inga run-way, a hanger made with lateralflanges adapte-d to slide in said run-way of the sides, andball-bearings interposed between the bearing faces of said lateralflanges of the hanger and the bearing faces of said run-way in thesides.

3. An overhead carrier consisting of a exterior ofthe wheel, the rimsofsaid sides extending beyond the periphery of the wheel and.constitutingrims therefor, and being divided into a plurality ofspoke-like rimprojections, spacedapart, so as to be adaptedto straddleacross wire, said spoke-like rim-projections being providedgon theirinterior opposedfaces with recessesconstituting a run-way, a hanger madewith lateral flanges `adapted to slide in said run-way of the. sides,and means arranged to prevent the spreading of the sides apart by anyundue lateral strain on they hanger, and ball-bearings interposed,between the, bearing faces of said lateral flanges `'ef the hangerandthe bearing ,faces of said run-way in the sides.

4. An overheadl carrier consistingy of a.V

journal-pin, a wheel mounted centrally thereon, sides mountedlonsaidgjournal-,pin exterior ofthe wheel, the. rims of said sidesextendingl beyond the periphery of the wheel and i constituting rimstherefor, andbeing GEORGE HENRY DOWNS.
